This recipe has been a holiday staple for my family for years and it remains one of those treats that sparks instant nostalgia. I first made these clusters one December evening when I needed a quick no-bake dessert for a last-minute gathering. The combination of semisweet chocolate and butterscotch made the kitchen smell like a candy shop and everyone hovered around the counter while the mixture cooled. They are crunchy from the roasted peanuts and pillowy from the miniature marshmallows which balance sweet and salty in every bite. I reach for this whenever I need a fast, crowd-pleasing sweet to package for gifts or to set out at a potluck. What makes these clusters special is their simplicity and adaptability. You do not need advanced equipment or complicated technique, yet the finished bites feel indulgent and homemade. The marshmallows add lightness, the peanuts contribute texture, and the dual chips create a layered flavor that keeps people coming back for one more. Whenever I serve them, they disappear first, often prompting requests for the recipe. They are perfect for busy days when you want something impressive with minimal fuss.

Ingredients

• Semisweet chocolate chips, 1 cup: Choose a good quality brand for glossy melting such as Ghirardelli or Nestle. Semisweet gives a pleasant bittersweet edge that prevents the clusters from tasting overly sugary.
• Butterscotch chips, 1 cup: These contribute a caramelized, buttery sweetness that pairs perfectly with peanuts. If you prefer a more pronounced caramel flavor, use a premium butterscotch chip.
• Vegetable oil or shortening, 1 tablespoon: A small amount of neutral oil helps the chips melt smoothly and gives the clusters a shiny finish. Shortening works well if you want a slightly firmer set.
• Roasted lightly salted peanuts, 1 1/2 cups: Use shelled, roasted peanuts for crunch. The light salt enhances flavor without overpowering the candy. If you prefer no-salt, reduce the added salt elsewhere.
• Miniature marshmallows, 1 1/2 cups: These provide soft, pillowy contrast to the crunchy nuts. Use fresh mini marshmallows for the best texture; older marshmallows can be dry.

Instructions

Prepare the work surface Line a large baking sheet with waxed paper. Arrange measuring spoons and cups within reach so you can move quickly once the chips are melted. Having waxed paper ready is important because the chocolate sets fast and you will want to drop spoonfuls immediately. Melt the chips Combine the semisweet chips, butterscotch chips, and vegetable oil in a large microwave-safe container such as a glass measuring cup. Heat on high for 30 seconds, then stir vigorously. Repeat 15 to 20 second intervals, stirring between each, until the mixture is smooth and glossy. The oil helps keep the texture fluid and prevents graininess. Avoid overheating which can scorch the chocolate. Incorporate the mix-ins Quickly fold the roasted peanuts and miniature marshmallows into the melted chips. Use a sturdy spoon to ensure the nuts and marshmallows are evenly coated. Work swiftly so the marshmallows do not melt completely; you want them to retain some chew and shape within the clusters. Portion the clusters Drop spoonfuls of the mixture onto the prepared waxed paper. For uniform clusters use a tablespoon or small cookie scoop. You can make larger or smaller clusters based on preference. Tap the baking sheet gently to flatten any peaks and encourage even setting. Chill and store Transfer the baking sheet to the refrigerator for about 15 minutes or until set. Once firm, pack them into an airtight container in a single layer or separated by parchment to prevent sticking. They will keep for up to two weeks at room temperature in cool conditions, or up to three months frozen.

Storage Tips

Store the clusters in an airtight container to preserve crispness and prevent them from absorbing odors. If stacking, place parchment or wax paper between layers. At room temperature they remain good for up to two weeks in a cool, dry place. For longer storage freeze in a freezer-safe container for up to three months. To thaw, move to the refrigerator for an hour and then bring to room temperature before serving. Avoid storing near strong-smelling foods.

Ingredient Substitutions

If you prefer a different nut try roasted almonds or cashews using the same volume. For a nut-free option substitute toasted sunflower seeds or pretzel pieces. Swap butterscotch chips for white chocolate chips for a different flavor profile. Use coconut oil instead of vegetable oil for a slight coconut note, or omit oil and stir in a teaspoon of light corn syrup if you want a firmer set. Note how each swap changes texture and sweetness.

Serving Suggestions

Present clusters on a decorative platter garnished with extra whole peanuts or a light dusting of cocoa powder. They pair beautifully with strong coffee, milk, or a small scoop of vanilla ice cream for a more decadent treat. For party platters include small labels indicating allergens. These are perfect bite-sized favors and can be arranged in mini cupcake liners for a polished look. Try serving them alongside salted caramels for a variety of sweet and salty options.

Cultural Background

Clusters like these draw on classic American confection traditions that celebrate combining nuts, chocolate, and marshmallows. Variations of the concept date back several decades in home kitchens and community bake sales where no-bake sweets were prized for simplicity and portability. The combination of chocolate and nuts speaks to a long-standing preference for contrast in texture and flavor that appears in many regional candy variations across the United States.

Seasonal Adaptations

For holidays mix in red and green mini M&Ms for a festive look or add crushed candy cane at Christmas for a peppermint twist. In autumn swap butterscotch for pumpkin spice white chocolate and sprinkle with a pinch of cinnamon. For summer gatherings keep them chilled and offer alongside fresh berries. These clusters adapt easily to seasonal tastes while maintaining their quick assembly and travel-friendly nature.

Meal Prep Tips

Make a double batch and portion into small containers for grab-and-go snacks. Freeze individual portions in resealable bags for convenient treats that thaw quickly. Preparing the nuts and measuring the chips ahead of time saves minutes when you are ready to melt. Keep a small stash of waxed paper and disposable scoops in your pantry so assembling does not become a project.

These clusters are an easy, reliable way to create homemade sweets that look and taste like you spent hours in the kitchen. Whether for gifting, baking exchanges, or quiet weeknight indulgence, they bring joy with minimal fuss. Try them once and they are likely to become part of your go-to repertoire.
